Charging The Integrated Rechargeable Battery - Renkforce HFP-C2 Bedienungsanleitung

8. Charging the Integrated Rechargeable Battery

The USB connection on which the device is charged must have a resilience
of at least 500 mA. This is usually ensured at every USC connection of com-
puters. However, the device may also be charged with mains units offering a
higher resilience. In this case, the service life reduces accordingly.
Before first commissioning, the integrated rechargeable battery must be
charged completely first. The charging duration is approx. 5 hours with a 1
A-mains unit. A charge at the USB connection of a computer may take up to
10 hours.
• Connect the enclosed USB cable to the USB interface (12).
• Plug the other end of the USB cable into the USB connection of a computer or a
suitable USB mains unit.
• The charge display (13) lights up red while charging and goes out when the
integrated rechargeable battery is fully charged.
• Disconnect the USB cable again after charging.
• The operating time with one battery charge is 25 hours depending on volume
and use.
• The charge display at the upper right in the display (2) indicates the charging
state of the rechargeable battery. Recharge the unit when the charge condition
display shows an empty battery symbol.
